Problems solved by technology
[0004] The invention solves the problem that the wrench will be hindered by other steel bars when operating vertically. This design scheme utilizes the sleeve body and the wrench joint connected to each other on the same line. Wrench joint, when the wrench head rotates, it drives the steel bar to rotate

Embodiment 1
[0027] like figure 1 As shown, when multiple steel bars are vertically arranged on the same plane, when a wrench is used to clamp a steel bar vertically and force it to move, the movement curve of the wrench will be hindered by other steel bars, which increases the difficulty of operation. The invention can make the parallel connection between the wrench and the steel bar, the center lines of the three coincide, and can effectively avoid the interference of other steel bars.
[0028] like figure 2 As shown, a wrench socket for threaded steel bars, including a sleeve body 1, a wedge-shaped clamping block 2, a wrench joint 3 and a positioning cover 4; one end of the sleeve body 1 is fixedly connected to the wrench joint 3, and the other end is connected to the positioning The cover 4 is fixedly connected, the positioning cover 4 is provided with a through hole 41 for the threaded steel bar to enter, and the inside of the sleeve body 1 is provided with a circular channel 11 for...

The invention relates to the technical field of wrench sleeves, and discloses a wrench sleeve used for a thread reinforcing steel bar. The wrench sleeve comprises a sleeve body, wedge clamping blocks,a wrench joint and a positioning cover; one end of the sleeve body is connected with the wrench joint, the other end of the sleeve body is connected with the positioning cover, a through hole allowing the thread reinforcing steel bar to enter is formed in the positioning cover, a round channel allowing the thread reinforcing steel bar is formed in the sleeve body, a groove allowing the head of the wrench to be inserted is formed in the wrench joint, wedge grooves are formed in the inner wall of the round channel of the sleeve body, the wedge clamping blocks are arranged in the wedge grooves,the wedge grooves and the inner wall of the channel are in smooth transition, the wedge clamping blocks can slide back and forth in the grooves and the inner wall of the channel, when the thread reinforcing steel bar stretches into the sleeve body, two wedge clamping blocks do the radial opposite motion, thread sleeve is clamped, under the effect of friction force, the thread steel rotates along with the sleeve body. The reinforcing steel bar and the wrench can be connected, when the wrench rotates, the reinforcing steel bar is driven to rotate, interference of other reinforcing steel bars isavoided, use is convenient, practicability is high, the application range is wide, and the size is small.
Description
technical field [0001] The invention relates to the technical field of wrench sockets, in particular to the design of a wrench socket used for threaded steel bars. Background technique [0002] In construction work, operations related to steel bars are often encountered, especially threaded steel bars. When threaded steel bars are used, they usually need to be rotated and twisted to make the threads on the steel bars and the internal threads on other workpieces tighten each other. For example, with internal Threaded connecting sleeve. When performing this type of operation, the user will twist the steel bar to rotate through the wrench. At this time, the wrench is perpendicular to the steel bar, and the wrench clamps the surface of the steel bar to force the steel bar. However, in the actual process, there will be a situation where there are multiple parallel steel bars on a plane. At this time, other steel bars hinder the movement of the wrench, and even prevent the wrench...
